Chad casts a shadow that is 14.3 feet long. the straight-line distance from the top of chad’s head to the end of the shadow creates a 23° angle with the ground. how tall is chad, to the nearest tenth of a foot?

Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since the straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
